Description

  The present invention relates to a solar cell, and more particularly to a movable type and a configuration added to exhibit various functions.

  A device that converts sunlight into electric power (hereinafter referred to as a “solar cell”) in terms of promoting energy saving, preventing environmental destruction such as air pollution, and being able to be used semi-permanently without charging. ) Has been attracting attention in recent years.

In the first place, however, the amount of solar energy per unit area is small, so the power generated by the solar cell itself is small. As a result, only small power is used, such as transmitters from satellites and rain gauges installed in remote areas, and calculators. Not limited to power supplies. Further, even when used as a power source, for example, as shown in Patent Document 1 below, it is limited to an application that is supplementarily used for auxiliary charging of a battery as a main power source.
JP-A-11-267162

  In the end, solar cells are not only limited in application in terms of power generation, but for that reason they are inevitably low in production quantity and thus high in production cost, which is also the cause of not being widely used. For this reason, not only in terms of promoting energy conservation and preventing the destruction of the global environment, but also in terms of developing or pioneering new applications not only from the viewpoint of increasing the production volume of solar cells to lower product costs and expanding applications. Development of a power supply device using a technically effective solar cell as the means has been desired.

  In addition, even when used as a power supply device that does not need to be periodically fed or charged, replaced with a battery or the like in a remote place, development of more effective usage methods and new applications has been desired. Similarly, it is necessary to carry out construction work and negotiation with a third party, and to develop a more effective power supply system using solar cells in places where it is difficult to obtain stable power immediately due to noise and other reasons. Was desired.

  Furthermore, there has been a demand for the development of a technology that can use solar cells even in devices that consume relatively large amounts of power.

  The present invention has been made for the purpose of solving the above-described problems, and is basically a movable solar cell with wheels. In addition, a battery (including a storage battery) is used in combination. In addition, a plurality of solar cells can be connected. This makes it extremely effective in situations where, for example, only a small amount of power is used but it is difficult to arrange a power supply or to obtain a commercial power supply, or in troublesome places and situations, or other situations where power is temporarily required In addition, it is possible to use the battery, and in addition, a user's troublesome charging work or the like is minimized.

  Next, an application for which the above-described use is specifically made is found, and a configuration necessary for the application is added to make a more convenient device.

  Next, even if a certain amount of electric power is required, it is possible to cope with solar cells by paying attention to the fact that the necessary time is limited in time. Further, a plurality of solar cells are connected so that a certain amount of power can be supplied as long as there is sunlight.

  In the present invention, since the solar cell is movable, only a small amount of electric power is required. However, it is possible to supply electric power appropriately in a situation where it is difficult to arrange a power source, power arrangement or commercial power source.

  In addition, it can be used for systems that use a certain amount of power for a short time, so it is possible to expand the area where mobile phones can be used, for example, and install automatic observation equipment in extremely remote places. Become.

  In addition, since a plurality of solar panels are used, a certain amount of electric power can be used at a campsite or the like. In addition, display of construction sites at night, advertising towers, road guidance, etc. becomes more effective.

  Further, by using it in combination with various devices, it becomes possible to effectively cope with the occasional need for electric power or the like. As a result, the use of the solar cell itself is expanded.

Hereinafter, the present invention will be described based on the best mode.
(Example 1)
The present invention relates to a movable solar cell that can simply output electric power from a solar cell. FIG. 1 shows the overall structure of the solar cell of this example.

  In this figure, reference numeral 10 denotes a solar cell body, a so-called solar panel, in which a large number of L / E conversion elements that convert light energy from the sun into electrical energy are arranged in a plane and electrically connected, 33 Is a terminal (outlet) for outputting the electric power generated from the solar panel to the outside, 30 is a battery, and 60 is a hand-held car equipped with these.

  The wheelbarrow 60 can be installed by being moved by a person to a place where a solar battery is required or a place where the solar battery is sunny. For this reason, the vehicle body is a light-weight structure made of a frame member 61, and relatively large wheels 70 are attached to the front, rear, left and right thereof, and a hand pushing part 69 for a person to hold and push with a hand is provided above the rear part. In order to cope with the height of the sun depending on the time and season, the solar panel 10 itself has a front end rotatably attached to the rotating shaft 62 above the front part of the vehicle body, and a vertical direction above the rear part of the vehicle body. Is attached with an inclination adjusting portion 63.

  Further, the solar panel 10 itself has a main body formed on the flat plate 19 and can be detached from the vehicle body 60 together with the flat plate. However, the attaching / detaching mechanism for the rotating shaft, the disassembling mechanism, the wheel braking mechanism for fixing the whole at the use position, the connecting mechanism to the power consumption source, and the like are well-known techniques. For this reason, those descriptions are omitted.

In the present embodiment, a power supply device from a commercial power source or the like is not provided, but this is because the use for the purpose described later is mainly considered in order to reduce the overall weight.
(Example 2)
In this embodiment, charging from a commercial power source and supply to an electric device using the commercial power source are enabled. FIG. 2 shows the overall structure, and FIG. 3 shows the electrical system.

  In FIG. 2, 65 is a box in which this solar cell system is stored, 66 is a solar panel pedestal on the top, 33 is an input / output terminal, and 71 is a small wheel for moving the box. . Note that the power generation of this solar cell is about 50 W, and therefore the solar panel is about 1250 mm × 600 mm wide. In FIG. 3, 30 is a DC12V capacitor, 31 is a charger that converts AC100V to DC12V, 32 is a converter that converts DC12V to AC115V, and 34 is an overcurrent controller.

In this example or embodiment, charging from a commercial power source or a separate generator is possible, and AC 115 V can be supplied. For this reason, although AC115V is needed temporarily, it can be used as a power supply when the acquisition is difficult. In addition, the solar cell can be a main power source depending on the case, or can be replenished for charging from a separate power source. Specific applications include a quiet power source at a remote camping site or the like, and a power source for an indicator light or warning light at night in a construction site or accident site that is somewhat remote. In addition, when used as a power source for indicator lights and warning lights at night, a switch mechanism is also provided that cuts off the circuit that outputs the battery to the outside during the day, such as by manual or automatic switching by detecting sunlight. Of course, you can leave it.
(Example 3)
In the present embodiment, a plurality of solar panels can be connected. This is shown in FIG. In the figure, reference numeral 50 denotes a handcart generally used for transferring a load. Reference numeral 20 denotes a solar panel carried by the wheelbarrow, and a support member 28 is attached to the back surface with a hinge (not shown) so that it can lean on the flat surface in the direction of sunlight. Reference numeral 29 denotes an output electric wire, which is connected to a storage battery in a box with wheels carrying the movable solar cell of the previous embodiment (embodiment) via an overcurrent controller. For this reason, of course, a dedicated input terminal is mounted in the box. Thereby, it becomes possible to cope with a case where a certain amount of power is required temporarily. Needless to say, the movable solar panel of the first embodiment may be used.
Example 4
The present embodiment shows a specific application of the above embodiment. This is shown in FIG. In this figure, reference numeral 80 denotes a display panel which can display a character or the like by arranging a number of liquid crystal elements and LEDs on a substrate in a grid pattern, and its contents can be changed and controlled. It is an expression keyboard. 82 is a bulletin board, and 83 is an illuminating body for illumination on the top. 84 is an automobile. Hereinafter, the effect using the features of the movable solar cell of the present invention in application to these will be described.

The display board whose display contents can be changed can be used at a ceremonial occasion, an event, or the like, especially at a signpost at night. That is, in these cases, the place where installation is required is not always a bright place at night, and even if it is an urban area, the power for illumination is not always readily available. Therefore, the road guide at night is received by receiving power from the movable solar cell of the previous embodiment. The same applies to the light emitter that illuminates the bulletin board at night.
In addition to the above, a mobile phone may be equipped to ensure guidance.

  This is a supply to passenger cars, which is supplied so that the battery of an automobile does not discharge when a single person or the like makes a business trip for a relatively long time such as two to three weeks. In other words, there are many cases where there is no appropriate power source in the garage or parking lot, whether it is an individual or a company's single dormitory. Can be a hindrance to traffic. So we rented a movable solar cell for rental and installed it next to the car, and we will receive power supply so that the battery will not dry out. Further, if there is a movement by a third party, a system for contacting the owner with a built-in mobile phone may be provided.

  In addition to the above, although not specifically shown, it can be used for air supply to a pond, a beast house, or a warehouse with a blower or the like. In particular, in aquariums, zoos, and livestock industries, it may be necessary to temporarily circulate pond water, ventilate or collect dust, but this is convenient. Of course, it can be used for heating and the like.

  Further, by illuminating with a specific wavelength only at night in a relatively wide farm, it can be used to collect and kill only specific types of pests. At this time, if it is a mobile type, there is no need to install a trap light around.

  It can also be used to charge air to the minus side when a large number of people gather temporarily. Furthermore, it is of course possible to install it near the garbage dump after lunch at the exercise venue and use it for deodorization.

Further, it is not limited to the movable type, but of course, it may be used for performing a chemical action such as use for electrolysis of water under the spread of future fuel cells.
(Example 5)
This embodiment is used after being fixed. Today, a rain gauge, a snow gauge, a seismometer, etc. are installed in a remote place, and if there is rain, the amount thereof is transmitted to a nearby weather station. By the way, these loading places are not only many places that are simply inconvenient or inconvenient and it is difficult to obtain electric power, and there are many places where it is difficult to access them with vehicles such as cars. Therefore, a movable solar battery and a measuring instrument, a transmitting device, or a device incorporating them is carried as close as possible to the installation location by a passenger car, jeep or the like, and then moved manually to the installation location. At this time, it is very convenient if the automatic rechargeable power supply apparatus using solar power generation is equipped with wheels. Hereinafter, this usage will be described with reference to the drawings.

FIG. 6 shows the overall configuration of a semi-embedded mobile phone repeater. In this figure, reference numeral 40 denotes a relay processor, which incorporates a transmission / reception device 41, a clock mechanism 42 and the like. Reference numeral 43 denotes a determination device for the presence or absence of transmission / reception. Reference numeral 39 denotes a power line switch between the battery 30 and the relay processor 20. 44 is an antenna. As shown in this figure, this device is the original installation location, with the solar panel facing the sun, and the lower 1/3 of the box is buried in the ground (GL) and fixed. ing. The switch 39 from the battery 30 to the relay processor 40 is turned ON only when the transmission / reception determining unit 43 detects predetermined reception. Thereby, the relay processor 40 performs relay processing, that is, transmission with predetermined reception and amplification. When the process is completed, the transmission / reception determining unit 43 turns off the switch 39. This flow is shown in FIG.
On the other hand, since power is supplied to the battery 30 by the solar panel 10 as long as the sun is shining, transmission that requires a considerable amount of power is also possible, depending on the frequency of relay processing. Specific applications include relaying mobile phones on forest roads that are far away from the home and where people and cars are not very busy. Of course, the idea itself of this embodiment can be applied to the above-described automatic measuring machine. In addition to the above, a plurality of processes may be switched by an instruction from the management apparatus side. For example, it is possible to measure snowfall in winter and precipitation in other seasons.
As mentioned above, although this invention has been demonstrated based on the some embodiment, it cannot be overemphasized that this invention is not limited to them. That is, for example, the following may be performed.
(1) The solar panel is rotated according to time so that it always faces the direction of the irradiation destination from the moving sun depending on the application and conditions to be used. For this reason, a mechanism for appropriate rotation such as a timepiece with a calendar and a motor is provided. Or it has a means which collects the separate sunlight of a condensing lens system, and the means has the capability.
(2) In order to prevent dust from accumulating on the surface of the solar panel, a wiper is attached to periodically clean the surface.
(3) For example, the solar panel shown in FIG. 2 is designed such that the left and right portions are folded toward the center so that the width is narrowed for the convenience of movement in the room.
